MACHINE FOR WINDING- YARNS OR THREADS.

Application filed January 4, 1926, Serial No. 79,112, and in GreatBritain August 25, 1924.

This invention of improvements in mament of up and down movement and one chines for winding yarns or threads relates to machines for winding yarns or threads into cops or pirns or like bodies on spindles or tubes or bobbins or the like and its object is the provision of machines which enable yarns or threads, especially delicate yarns, to be wound into cops or pirns or like bodies of regular formation at high speeds with a minimum of rubbing of yarns or threads being wound and without any rubbing of yarn or thread wound on spindles or the like, facilitate the work of attendants in piecing broken threads, in removing completed or full cops, pirns or the like from spindles, the restoration or set ting of the machines into condition for the commencement of the winding of fresh cops, pirns or the like, the adjustment of the machines for forming cops, pirns or the like of any required diameter and length and consequent inclination of the chase or conical portion, and are cheap in construction.

With this object the invention consists in a machine as hereinafter to be described in detail with reference to the accompanying drawings in which there is employed mechanism comprising a number of spindles with blades which are revolubly mounted in bearings supported by a stationary rail forming part of the framework providing support for parts of the machine and with bearings for shafts and are furnished respectively with driven friction members mounted around, in engagement with and movable up and down lengthwise of them and driving friction members mounted around said bearings and means for revolving the driving friction members and comprising along therewith thread guides carried up and down and moved progressively by and easily adjusted upon screws movable axially up and down and provided one for each spindle, and all worked up and down by arms on an oscillating shaft and revolved by means of bevel wheels mounted revolubly in the said. rail to receive motion by means of bevel wheels engageable and disengageable with and from them and all turned by means of a revolving shaft and each screw and the spindle with which it co-operates can be started and stopped separately from the other like screws and spindles. The invention also provides in such a machine means enabling one adjustadjustment of progressive movement to serve for a plurality of thread guides, convcnient and efficient means for enabling the moving thread guide used with a spindle to bring about with certainty the stoppage of the spindle and of the progressive move ment of the thread guide itself when a cop, pirn or the like is completed, stops for facilitating accurate return of thread guides to the positions for starting the formation of cops, pirns or other bodies and capable of being easily set in position for the formation of cops, pirns or the like of any length requisite, means for transmitting revolution from the bevel wheels in the rail to the screws obviating danger of binding in movement, thread guides of simple form providing easily revoluble parts to minimize rubbing of yarns and other details as hereinafter described in reference to the drawings and set forth-in the claims following.

This invention is illustrated in the accompanying drawings which shows a winding machine forming an illustrative em bodiment of the invention.

11 is the frame work of the machine and 12 is a stationary rail provided therein for the support of spindles 13. The spindles 13 of which there may be any number in a row comprise spindle bearings 14 fixed in the rail 12 and spindle blades revolubly mounted in the bearings 14 and furnished respectively with driven friction members 16 mounted around, in engagement with and movable up and down lengthwise of them, by which friction members 16 the spindle blades 15 receive motion. In the case illustrated the spindles 13 are of the construction forming the subject of United States Letters Patent No. 996,530 dated June 27th, 1911, and described in the specifications filed in respect of applications for British Letters Patent No. 2,335 dated January 31st, 1910, and No. 196,498 dated May 22nd, 1922, by the present applicant and Alfred Seeley in which the driven friction members engaged with the spindle blades are movable on and lengthwise of them so as never to bear the weight thereof or of bobbins or other objects or yarn or thread thereon ant. made ordinarily to bear with their own weight only on driving friction members mounted around the spindle bearings so as to be capable of being revolved independently of and always out of contact with the spindle blades. In the case shown also, the driven friction me1nbers 16 are provided with circumferential flanges 17 by means of which they may be lifted and internal conical openings 18 on their lower sides whereby they may be made to receive and to become engaged with conical parts on the driving friction members 19 which are formed as pulleys adapted to receive motion by means of tapes 20. In the case shown there is a rail 12 with spindles 13 at each side of the machine and each tape 20 is made to drive two pulleys 19 one at each side of the machine and to receive motion by means of a tin roller 21 on a shaft 22 mounted in pedestals 23 in the frame work 11 at each end of the machine. For each tape 20 there is provided a tightening pulley 24 carried on an axle 25 mounted and held by pins 261 in forked levers 26 pivoted on a rod 27 extending along the machine and fixed in the end frames of the framework 11. The levers 26 are under the influence of springs 28 hooked to them and to screwed and nutted rods 29 passed through and adjustable in brackets 30 fixed adjustably by Set screws on a rod 31 secured in the end frames so that each tightening pulley 24 shall keep taut the tape 20 with which it is used.

Except for parts of the mechanism of the machine, for example the tin roller 21 and jockey pulleys 24, which co-operate with the spindles 13 on both sides of the machine, similar parts are provided on and in connexion. with each rail 12 and the spindles 13 carried thereby. For simplicity however description will commonly be given of the mechanism co-operating with the spindles 13 carried by one rail 12.

The shaft 22 is made to receive revolution in any suitable way and is shown as provided with step pulleys 32. On the shaft 22 a sprocket wheel 33 is fixed which, by a chain 34, communicates motion to a sprocket wheel 35 fast on a shaft 36. A Wheel 341 pivoted on a bracket 342 on an end frame 11 is provided to deflect the chain 34 clear of a shaft 85 mentioned later. The shaft 36 and another shaft 37 parallel to it are mounted to extend lengthwise of the machine in hearings in the sides of a box 33 fixed to one end frame of the machine and providing bearings for a transverse shaft 39 extending transversely of the machine and also hear ings for two short shafts 40, extending lengthwise of the machine. A toothed wheel 41 is fixed on the shaft 36 to drive a toothed wheel 42 fixed to a cam 43 with an oblique cam groove 44 engaged by a bowl 45 on a pivot fixed in an arm 46 fast on the shaft 39. The cam 44 is mounted loose on the shaft 37. A toothed Wheel 47 fast on the shaft 36 drives a toothed wheel 43 fast on the shaft 37. Collars 361 and 371 applied around the shafts 36 and 37 with a shoulder on the shaft 36 and the cam 43 position the shafts 36 and 37 in the box 38. Fast on the shaft 39 are two bevel wheels v49 in gear respectively with bevel wheels 50 on the short shafts 40. Each short shaft 40 bears an arm 51 fast upon it and formed with a slot in which a slide block 52 is mounted to be movable radially relatively to the shaft 40 and each slide block 52 surrounds and is engaged by a stud 53 fixed in position in the slot of a slotted arm 54 fixed upon one of two shaft-s 55 extending along the machine, and mounted in brackets 551 secured on the end frames 11. The studs 53 being adjustable in the arms 54 in which they are respectively mounted afford means of adjusting the extent of oscillation of the shafts 55 effected by the revolution of the cam 43 and in the case shown the disposition of the wheels 49, 50 is such that the shafts 55 oscillate eppositely as regarded from either end of the machine. The groove 44 of the cam 43 is shaped so that the cam 43 being revolved will oscillate each shaft 55 in the manner requisite.

Near each spindle 13 a bevel wheel 56 with a central hole is mounted by means of a sleeve 57 formed upon it to revolve in the rail 12 and to present its central hole parallel to the axis of the spindle 13 near it and is secured in position by a collar 58 secured upon the sleeve 57. In the case shown, each bevel wheel 56 is furnished with two depending rods Through the central hole of each bevel wheel a screw 60 is mounted to be slidden. Each screw 60 is provided with acollar 61 fast upon it, below the bevel wheel 56 through which it passes and in this collar 61 are formed holes allowing passage to the rods 59 depending from the bevel wheel 56 so that the rods 59 and collar 61 enable the bevel wheel 56 to turn the screw while the screw 60 is free to be moved up and down in the bevel wheel 56. In the case shown each screw 60 is provided at its lower end with a collar 62 formed with a circumferential groove 63 receiving a dog 64 pivoted in the end of one of a number of arms 65 fast upon one of the shafts There are as many arms 65 on each shaft 55 as there are spindles 13 mounted inthe adjacent rail 12. The cam 43 oscillating the shafts 55 thus causes the screws 60 to move up and down. Near each spindle 13 there is secured to the rail 12 a bracket 66 forming bearing for a short shaft 67 on which a bevel wheel 68 is splined so as to be movable axially into and out of engagement with the bevel wheel 56 adjacent to such spindle 13. Each shaft 67 has a toothed wheel 69 fast upon it and is held in position axially by a collar 70 fixed in position upon it by a screw. Each bevel wheel 68 is formed with a collar in which is a circumferential groove 71 in which engages a pin 72 secured in a lever 73 pivoted on a bracket 74 secured on a rail 75 forming part of the machine framework. A stud 76 adjustably secured in a slot 7 7 in the lever 73 is connected by a link 78 to the lever plate 79 of a stop motion mechanism. Each shaft 67 has fixed upon it a detachable toothed wheel 69 in engagement with a toothed wheel 80 detachably fixed to a bevel wheel 81 mounted revolubly about a stud 82 fixed adjustably in a slot in an arm 83 secured and adjustable around a cylindrical part of the bracket 66. The wheels 69, 80 may thus be used as change wheels and be replaced by other wheels of different relative diameters in case of need.

The bevel wheel 81. is made to gear with one of a number of bevel wheels 8 1 fixed and adjustable lengthwise of a shaft 85 extending along the machine and mount ed revolubly in bearings in brackets 851 on the machine framework and on one end of the shaft 85 there is fixed a ratchet wheel 66 by which the shaft 85 is made to receive a step by step revolution in one direetion in the working of the machine. Preferably means are provided for adjusting the amount of turning imparted to the ratchet wheel 86 at each movement. In the case shown in Figs. 1 2 and 3, the ratchet wheel is made to receive motion by means of a pawl 87 pivoted to an arm 88 mounted oscillatably around the shaft 85 and having fixed adjustably upon it, by a set screw, a block 89 formed with a hole to receive the arm 88 and connected by a stud 90 and a connecting rod or pitman 91 to a stud 92'fixed and adjustable in a slot 93 in a plate 94 screwed to terminal lateral projections on radial arms 95 extending oppositely from a boss 96 fixed by a set-screw on the end of a short shaft 97 mounted to revolve in a bracket 98 on the frame work. Fast on each shaft 97 is a sprocket wheel 99 made to receive motion by a chain 100 from a' sprocket wheel 101 mounted on the shaft 37. By adjustment of the position of the stud 92 in the plate 9 1 or of the block 89 on the arm 88 or both, the extent of movement of the pawl 57 in each stroke and consequently the extent of turning given to the ratchet wheel 86 at each movement can be adjusted. A spring 102 inserted in a hole in the arm 88 is made to bear against a tail 103 on the pawl 87 to ensure that it shall engage a ratchet wheel 86. A pawl 10 lpivoted on a bracket 105 on the end frame and under the in fiuence of a spring 1041 engaged with the bracket and coiled around a boss thereon is provided to engage the ratchet wheel 86 in order to prevent it from being moved oppositely to the motion imparted to it by the pawl 87. Around each screw 60 is mounted slidably a thread guide carrier 106 provided with a spring pressed dog 107 mounted to slide in a hole providing parts of smaller and larger diameter to guide the dog 107.

A similar guide carrier and set of cooperating parts are provided for each spindle 18 and the screw 60 used with it and so for simplicity in the description'rei erence will commonly be made to one part as an example of all instead of explicitly to each of the several similar parts.

A. spring 108 surrounding the stem of the dog 107 of each carrier 106 and abutting at one end against a shoulder on the dog 107 and at the other against the end of the larger part of the hole in the carrier 106 ordinarily holds the dog 107 in engagement with the thread of the screw 60. A knob or head 109 fixed on the stem of the dog 107 provides means by which the dog 107 and consequently the carrier 106 can be disengaged from the thread of the screw 60 in order to be moved relatively thereto. Below 1 the guide carrier 106 each screw 60 is pro vided with two nuts 110 adjustable upon it and serving one to lock the other which form an adjustable stop to limit the extent to which the carrier 106 can be moved downwardly when. the dog 107 is disengaged .from the thread of the screw 60. The carrier 106 is shown as formed with a projecting arm 111 having a hole, and by a set screw 112 there is secured a rod 113 formed with a transverse opening and divided at one end and furnished with a screw 114: by which the parts of the divided end may be drawn together. A rod 115 extending in the direction of the length of the machine is secured in the divided end of the rod 113 and formed with a hole in one end and in this hole a headed pin 116 is pushed so to remain lined and around the shank of the rod 113 a thread guide 117 in the form of a roller of any appropriate material, for example vulcanized fibre, is mounted free to be revolved. Each carrier 106 is provided with a tripping motion actuating part 10 bring a stop motion mechanism into action. In the case shown the tripping motion actuating part is a projection 118. The carriers 106 must be prevented from being turned with the screws 00 and so in the case shown each carrier 106 is made to surround a sruide rod 119 inserted at its lower end in a hole in the rail 12 and extending parallel to the axis of the spindle 13 with which it is used. At its upper end the guide rod 119 is secured in a guide block 120 shown as sur onndin and gui "1g the cooperating screw and also shown as socured by a bolt 121 to a bracinirt 12 sun rounding and secured. to a rod 12;} extending lengthwise of the machine and secured in brackets 124: on the end frames of the machine framework 11.

\Vhilo any suitable tripping mechanism may be used for a tuating a stop mot on mechanism for stopping the progressive movement of thread go 117 along a screw 00 concurrently with the stoppage of the spindle blade wi h which such guide 117 cooperates, the invention provides a simple and efficient tripping mechanism by which the arrival of a thread guide 117 at the point in its progressive motion at which the winding of yarn into or on a cop, pirn or other body or form on the spindle 13 is to cease will stop the revolution of the spindle blade 1.5 and the progressive movement of the thread guide 117. As shown in the drawings each tripping mechanism comprises a lever 125 mounted so as to be capable of oscillation on a stud 120 screwed into the rail 12 adjacent to the screw 00 and spindle 13 with which the tripping mechanism is to cooperate and cranked or bent so as, while being pivoted on the front of the rail 12, to present ordinarily its upper part parallel to and near to the screw 00 and its lower part extending vertically down below the rail.

Each lever 1 5 is provided above the rail 12 with a contact part 127 in the form of a collar adjustable upon it and fixed by a screw 1.28 and presenting an inclined, in the case shown a conical, end 129 which in the ordinary position of the lever 125 is in the path of the upward movement of the projection 118 in order to l e moved thereby for the lever 125 to be oscillated about the stud 126. Below the rail 12 on each lever 125, a linger 130 with an inclined end is mounted adjustably and fixed in position by a screw 131 to present its inclined end extending just below one arm of a catch lever 132 pivoted on the lever plate 7 9 of the stop motion mechanism so that when the lever 1.25 is moved by the projection 118 the one arm of the catch lever 132 is lifted. Each guide block 120 is shown as formed with a slot 133 affording guidance to the upper end of the lever 125 in its lateral movement. The lever plate 79 is formed wit-h two arms 13% extending inwardly towards the inteior of the machine and made to present lifting parts 135, in the case shown made adjustable in extent of upward projection by being formed as lock nutted screws. The

lifting parts 135 are made to extend below and ordinarilyjust to touch the lower ends of two parallel. lifting rods 136 mounted so that they may be slidden up and down in holes formed in the rail 12 and are ordinarily held by the lifting parts 135 in position to present their upper ends below and just clear of the circumferential flange 1'? of the axially movable driven friction m mber 10 of the adjacent spindle 13. The li ;ing rods are mounted at diametrically opposite sides of the spindle axis so that when raised they will lift the flange 17 without causing it to bind on the bearing carrying it. it their lower ends the lifting rods 136 are formed with collars 1361 and spiral springs 1362 are applied around the rods 136 between the collars 1361 and the rail 12 to hold the rods 136 down in contact with the lifting parts 135. In lifting the flange 17 the rods 136 act as brakes therefor.

The stop motion mechanism used with each spindle 13 and screw 00 is of a well known construction. In each stop motion mechanism, each lever plate 79 pivoted on a bracket 138 screwed to the rail 1.2 is held in ordinary position for winding to continne by a bowl 139 on the lever plate 79 being engaged as shown with one notch of a spring 1410 screwed to the rail 75 and when moved into position to stop the spindle blade 15 and the progressive movement of the thread guide carrier 106 becomes held in that position by the bowl 139 being engaged in another notch of the spring. 140. There is pivoted on each lever plate 79 a hook lll with a catch part 142 capable of being engaged with and released by a catch part 143 on the catch lever 132. F or each yarn to be led to and wound by means of the spindle blade 15 with which the lever plate 79 is used there is pivoted on the lever plate 79 a hook 1% similar in its lower part to the hook 141 and furnished with an arm 145 carrying a roller 146 under which yarn may be led. The hooks 1 11, 1441 used with each lever plate 7 9 are provided respectively with catch parts 147 and 1 18 at their lower ends which ordinarily are held out of the path of a beater 149 secured on a rocking shaft 150 oscillated in the machine framework 11 by means of the revolving shaft 37 acting through a crank 151 thereon anda pitman 152 connecting such crank 151 with a stud 153 in an arm 154 secured on the one shaft 150 which bears an arm 155 with a stud 156 connected by a pitman 57 to a corresponding arm 155 on the other shaft 150.

In an alternative means shown in Fig. 7 for adjusting the rate of turning of the screws and progressive movement of the thread guides 117 thereon, a ratchet wheel 158 on the shaft 85 is revolved step by step by means of a pawl 159 pivoted on a lever 160 mounted to oscillate around the shaft 85 and connected by a stud 161 to a connecting rod 162 corresponding to the connecting rod 91 in Figs. 1, 2 and 3. A spring 163 is screwed to the lever 160 and made to bear on the pawl 159 in order to ensure engagement of the pawl 159 with the teeth of the ratchet wheel 158. In order to prevent the ratchet wheel 158 from being turned in the direction contrary to the movement effected by the pawl 159, a pawl 164 pivoted on a stud 165 secured to the brackets 851 and furnished with a spring 166 screwed to it and bearing on the pawl 164 is provided. In order to adjust the extent of movement imparted to the ratchet wheel 158 by the pawl 159 in each movement of the lever 160, there is provided an adjustable mask 167 in the form of a curved plate extending around a portion of the circumference of the ratchet wheel 158 and presenting an arm directed inwardly of the curved plate and ending in a curved part 168 partly surrounding and secured by a screw 169 passed through it on a collar 170 adjustable and fixed by a set screw 171 in position around the boss 852 of a bracket 851. By the mask 167 being adjusted around the boss 852 the pawl 159 may be kept out of engagement with the teeth of the ratchet wheel 158 for a smaller or a greater part of its movement and thus made to effect a greater or less movement of the ratchet wheel 158.

In setting the machine ready for winding of yarn to begin, yarns to be wound are attached to the spindle blades 15 or pirns, bobbins or other bodies thereon as is convenient from time to time in the use of the machine the thread guide carriers 106 are liberated from the threads of the screws 60 and moved down to the position at which yarn may pass from the thread guides 117 to the spindles 13 or bodies thereon at the places at which the lowest windings at bottoms of cops, pirns, bobbins or other bodies are to be formed and the nuts 110 are adjusted on the screws 60 for the upper nuts 110 to be then in contact with the thread guide carriers 106 in order that a subsequent winding may be begun at the same level and the contact parts 127 are set on the levers 125 in positions corresponding to the intended length of the pirns, bobbins or other bodies into which yarn is to be wound, and the lever plate 79 is brought into position for the catch parts 142 to become engaged with the catch parts 143 and to be held thereby out of the paths of the heaters 149. lhen the tin roller 21 being set in motion, motion is transmitted by the tapes 20 to the driving friction members 19 and so to the driven friction mem bers 16 and spindle blades 15 and, in the case illustrated, the conical form of the engaging parts of the driving friction members 19 and driven friction members 16 together with the transmission of motion by the tapes 20 guards against slip in the driving of the spindle blades 15. Concurrently with the transmission of revolution to the spindle blades 15 motion is transmitted by the sprocket wheel 33, chain 34 and sprocket wheel 35 to the shaft 36 and from the shaft 36 by the toothed wheels 41 and 42 to the cam 43 and from the cam 43 by the arm 46, shaft 39, bevel wheels 49, 50 to the shafts 40, and arms 51 and 54 to the shafts 55 which are made to oscillate and by the arms and collars 62 to move the screws 60 up and down and the screws 60, being moved up and down, cause the thread guides 117 to guide yarn in layers up and down the chase of the cops, pirns, bobbins or other bodies into which they are to be wound. Each sprocket wheel 101 on the shaft 37 transmitting motion by a chain 100, sprocket wheel 99, shaft 97 and crank arm 95 to a pitman 91 and an arm 88 and pawl 87 to a ratchet wheel 86 causes a shaft 85 to receive a step by step revolution which being transmitted by the bevel wheels 84, 81, wheels 80, 69, shafts 67 and bevel wheels 68 to the bevel wheels 56 causes the screws 60 worked up and down by one shaft 55 to receive also an intermittent revolution causing the thread guide carriers 106 and thread guides 107 gradually to be raised. A similar gradual raising of the thread guide carriers 106 and thread guides 117 is effected by the alternative mechanism described with reference to Fig. 7 if used. The crank 151 upon the shaft by means of the pitman 152 imparts an oscillatory movement to the one shaft 150 and the arms 155 on that shaft 150 by the pitman 157 and the arm 155 to which it is connected transmits an oscillatory motion to the other shaft 150. Should any yarn being wound break or come to an end so that a roller 139 falls and the corresponding hook 144 is released and allowed to pass into the path of the corresponding heater 149 which then, pulling on the hook 144 so released, moves the corresponding lever plate 79 and thereby by means of the arms 134 and lifting rods 136 raises the corresponding driven friction member 16 out of engagement with the driving friction member 19 and causes the said lifting rods 136 to act as brakes against the flange 17 and to stop the spindle blade 15 quickly and at the same time by means of the connected link 78 and lever 73 disengages from the bevel wheel 56 on the screw 60 used with the said spindle blade 15 the bevel wheel. 68 which drives it, so that when a spindle blade 15 is stopped progressive movement of the thread guide 117 used with it is also stopped and in the continuance of winding, after the broken or ended yarn has been pieced, any irregularity of form of the cop, pirn or other yarn body being wound due to movement of the thread guide 117 while the spindle blade 15 stopped is obviated. When a thread guide carrier 106 arriving at the summit of the intended progressive movement duringan upward movement of the screw (30 carrying it, it comes against the co-operating contact device 127, the lever 125 carrying that con-- tact device 127 is turned about its pivot 126 and by the arm 130 upon it raises the one arm of the co-operating catch lever 132 and allows the co-oper-ating hook 14-1 to pass into the path of the corresponding beater 149 so that the lever plate 79 being moved will stop both the spindle blade 15 and the progressive movement of the thread guide 117 as in the former case.

It will be seen that adjustment of the position of the stud 53 in either of the arms 54 will adjust the extent of up and down movement of the screws 60 at the corresponding side of the machine and that the studs 53 may be adjusted for the screws 60 at one side of the machine to have an up and down movement different in extent from the up and down movement of the screws 60 at the other side of the machine.

It will also be seen that by adjustment of the places of connexion of the pitmans 91 or by adjustment of the mechanism described with reference to Fig. 7, the rate of the progressive movement of all the thread guides 117 at either side of the machine may be adjusted and that the one adjustment will effect all the thread guides 117 at the one side of the machine and that the rate of the progressive movement of the thread guides 117 on the one side of the machine may differ from the rate of the progressive movement ofthose on the other. In the case shown in the drawings, the wheels 69 and 80 being changeable in position or easily capable of removal for the substitution of others, afford an easy means of making greater changes of progressive movement of the thread guides 117 than can be effected byadjustment of the connexions of the pitmans. 91 or the mechanism described with reference to 7 should they be requisite at any time, and also make it possible for different thread guides on-one side of the machine to receive different progressive movements should such an adjustment ever be needed.

It will also be seen that although the drawings show a machine with spindles at two sides, the invention is not restricted to em bodiments in a machine with spindles two sides, since each side of the machine forms a complete embodiment of the invention although for simplicity in the case il lustrated motion is transmitted from parts at one side of the machine to parts at the other side thereof.

What I do claim as my invention and desire to secure by Letters Patent is 1. A yarn winding machine having a fran'iework with bearings for shafts and comprising a stationary rail for earryilur spindles and mechanism comprising spindle hearings carried by said rail, spindle blades revolubly mounted in said bearings and furnished respectively with driven friction members mounted around, in engagement with and movable up and down lengthwise of them, driving friction members mounted around said spindle bearings to receive connexion of and to transmit motion to said driven friction members, and means for rcvolving said. driving friction members and in combination therewith a shaft to oscillate in said framework, means for oscillating i said shaft, arms fast on said shaft, revoluhlc screws movable up and down axially, means for connecting said screws and said arms. bevel wheels with central holes surrounding said screws and revolubly mounted in said rail, means for transmitting revolution from said bevel wheels to said screws, bevel wheels severally movable axially for engagement with and disengagement from the bevel wheels around the screws, means for supporting said axially movable bevel wheels, a revoluble shaft mounted in said framework, means for transmitting revolution to said axially movable bevel wheels from said revoluble shaft, means for revolving said revoluble shaft comprising a pawl and ratchet wheel, means for varying the extent of turning movement imparted to said axially movable bevel wheels in the movements of said paw-ls, guide rods parallel to the axes of the spindle blades, means for supporting said guide rods, thread guide carriers each with a tripping mechanism actuating part and surrounding a screw and engaging-a guide rod movable lengthwise of such screw and guide rod, thread guides carried by said thread guide arriers, spring pressed dogs in said thread guide carriers severally engageable with and disengageable from said screws, and lifting rods mounted in pairs to slide up and down in said rail parallel to the axes of said spindle blades and presenting their upper ends beneath said driven friction members.

2. A yarn Winding machine as claimed in the preceding claim 1, characterized by the thread guide carriers having each a part to actuate a lever, by levers fulcrumed on the stationary rail and each presenting a part for tripping a stop motion mechanism for action and by collars With inclines fixed adjustably on said levers to receive contact of and actuation by .the cam surfaces of said thread guide carriers.

3. A. yarn Winding machine as claimed in the preceding claim 1, characterized by stops adjustably fixed on the screws below the thread guide carriers.

4;. A arn Winding machine as claimed in the preceding claim 1, characterized by means for adjusting the movement imparted by the pawl to the ratchet Wheel.
